Elderly Dog Chases Squirrel For First Time In Years (Video)

Finally, after years and years, an elderly dog gets to chase a squirrel for the first time, and we have never seen anything more heartwarming. Its reaction to its owner repeatedly saying the word "squirrel" at him is the so human - from confusion to understanding to disbelief and then to pure, unadulterated joy. And the joy of a senior dog is unparalleled to anything else. 

It's enough for something as small and innocent as chasing a squirrel to bring energy and light into the eyes of a dog. And this video, while adorable and funny, will also make you want to get out the tissue box.
